ITEM 7.01. Regulation FD Disclosure.

Attached as Exhibit 99.1, which is incorporated herein by reference, to this Current Report on Form 8-K is a copy of the Company’s presentation presented at our Annual Meeting of Stockholders on May 29, 2009.

The Securities and Exchange Commission has generally permitted oil and gas companies, in their filings with the SEC, to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. We use the terms “probable,” “possible” and “non-proved” reserves, reserve “potential” or “upside” or other descriptions of volumes of reserves potentially recoverable through additional drilling or recovery techniques that the SEC’s guidelines may prohibit us from including in filings with the SEC. These estimates are by their nature more speculative than estimates of proved reserves and accordingly are subject to substantially greater risk of being actually realized by the company.

Exhibit 99.1

Annual Meeting of Stockholders Houston May 29, 2009

This is an oral presentation which is accompanied by slides. Investors are urged to review our SEC filings. This presentation contains certain forward-looking statements regarding various oil and gas discoveries, oil and gas exploration, development and production activities, anticipated and potential production and flow rates; anticipated revenues; the economic potential of properties and estimated exploration costs. Accuracy of the projections depends on assumptions about events that change over time and is thus susceptible to periodic change based on actual experience and new developments. Endeavour cautions readers that it assumes no obligation to update or publicly release any revisions to the projections in this presentation and, except to the extent required by applicable law, does not intend to update or otherwise revise the projections. Important factors that might cause future results to differ from these projections include: variations in the market prices of oil and natural gas; drilling results; access to equipment and oilfield services; unanticipated fluctuations in flow rates of producing wells related to mechanical, reservoir or facilities performance; oil and natural gas reserves expectations; the ability to satisfy future cash obligations and environmental costs; and general exploration and development risks and hazards. The Securities and Exchange Commission permits oil and gas companies in their filings with the SEC to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. SEC guidelines prohibit the use in filings of terms such as "probable," "possible," P2 or P3 and "non-proved" reserves, reserves "potential" or "upside" or other descriptions of volumes of reserves potentially recoverable through additional drilling or recovery techniques. These estimates are by their nature more speculative than estimates of proved reserves and accordingly are subject to greater risk of being actually realized by the company. Certain statements should be regarded as "forward-looking" statements within the meaning of the securities laws. These statements speak only as of the date made. Such statements are subject to assumptions, risk and uncertainty. Actual results or events may vary materially.

Endeavour at a Glance Endeavour Acreage Endeavour Production Endeavour Developments 3 major development projects in the UK moving forward Sale of EEN for $150 million Disciplined and successful E&A process Recent launch of onshore US exploration campaign 2008 financial results Discretionary cash flow $121 million Ending cash balance $59 million Production at higher end of forecast range 8,800+/- BOEPD (pro forma 4,000-5,000 BOEPD) Reserve replacement 175% Valuable hedge position @ $80 oil (4Q08 gain in excess of $100 million) Strong balance sheet and cash position (sustainable, self-funded business model)

Sale of Norwegian Subsidiary - Deal at a Glance Rationale Made money for investors Adds financial flexibility and strength Gives ability to capitalize on drilling successes in United Kingdom Allows opportunity to actively pursue growth strategy of shorter-cycle, lower cost opportunities in US Deal Metrics Sale price - $150 million cash consideration (6x return) Reserves sold - 6.0 MMBOE 2P or 19% of total; $25 / 2P BOE Financial Impact Net debt approximately $50 million post transaction

Our Strategy - Balanced and Sustainable Growth Production Portfolio of high-quality producing assets Upside performance potential Development Active advancement of multiple projects to assure near-term growth Strive to operate or have influence in driving performance Exploration Disciplined approach to evaluation and risk management Run exploration as a business M&A Active and opportunistic participation in value added transactions (e.g.- sale of Norwegian subsidiary) Finance Self-funding enhanced by hedged oil and gas production Strong cash position Quiet capital structure

The discovery was made in a three-way Lower Cretaceous sandstone stratigraphic wedge trap within the R Block focus area. Gas and oil were logged, sampled and pressure tested. A drill stem test in the gas leg flowed at a rate of 41 MMCFPD and 2,300 BCPD from perforations in the upper 20 feet of a 77 feet hydrocarbon column. The development is being fast-tracked to achieve production in 2010.

The Cygnus Fault Block III appraisal well was drilled and flow tested at a rate of 32 MMCFPD from the targeted Rotliegendes Leman reservoir. Both well tests exceeded pre-drill expectation. To date, approximately 500 BCF gross have been discovered and appraised with additional reserves yet to be confirmed in Fault Blocks IIa, IV and V. Upside reserves could be 1.0+ TCF.
